Hamamatsu Photonics Europe Si photodiodes S9219

The S9219 is a silicon photodiode designed for applications such as photometry and luxmeters, featuring a spectral response range of 380 to 780 nm, which closely aligns with the sensitivity of the human eye. It utilizes an accurate visible-compensated filter and is housed in a robust metal package with a BNC connector, providing a photosensitive area of 11.3 mm in diameter. The device operates with a maximum reverse voltage of 5 V and can function within an operating temperature range of -20 to +50 ¬8C. The S9219 exhibits a peak sensitivity wavelength of 550 nm with a photosensitivity of 0.24 A/W at this wavelength. Under standard illumination conditions (100 lx, 2856 K), it generates a short circuit current of 4.5 ¬µA and has a dark current of 50 pA at a reverse voltage of 10 mV. The rise time is specified at 2.5 ¬µs, and the terminal capacitance is 1100 pF at 0 V and 10 kHz. Engineers considering the S9219 should note its specifications for reliability and performance in environments where dew condensation is a concern, as this can affect the product's characteristics.
